Question about Garmin Rino 120 2-Way Radio

3 Answers

Batteries in my Rino 120 don't last very long

My Rino 120 uses 3 AAA batteries. Originally I could get about 4 hours of continuous GPS use and moderate radio use. Now I barely get 1 hour of GPS use only. The unit gets very warm when in use. It will use a set of batteries after 6 hours when off. Anyone else have similar problems?

Check if the Ptt buton is not pressed by itself Check if all the features are running well because heat is not a good sing.

3 AAA batteries won't last long if your transmitting in higher powered GMRS. But if your not getting much time out of the batteries when just using gps, then it could be a few things. 1.. If your using rechargables you could have a bad cell thats no longer taking a full charge. 2.. if your using regular batteries use alkalines that are of good brand. 3.. The fact that the unit seems to be running hotter than usual could be another clue. A failed integrated circuit will usually draw alot more current. Usually what will happen in this situation if your hooked up to a power supply insted of batteries is the unit in question will get warm an draw more current slowly... the warmer it gets the more current draw... if you were using this on a power supply what would happen is it would eventually draw so much current that it will pop a fuse. In your situation your running on batteries.... the increase in current draw will just drain the batteries faster. Its a common problem with electronics... usually you can tell its a failed integrated circuit (IC) because the piece of electronics will blow fuses.... but not fast... sometimes it will take an hour for the IC to heat up enough and draw the appropriate amount of current to "pop" the fuse. At that point the IC is drawing alot of current. Thats a big clue.... a dead short pops fuses fast.... a bad IC will take a while to pop a fuse. Try checking the batteries as well as the advice in Solution#1 by sgregg. What could be happening is there is an IC that has gone bad inside the unit. The IC is running hotter and drawing more current as it heats up... causing the batteries to drain. Its just a guess.... its hard to speculate since I can't test the unit myself. Check the simple stuff first like batteries. Take care Bra

I believe its 3AA's and it SHOULD last 15 hrs of life. You should probably check the terminal heads and clean them real good you might be shorting somewhere in the connection.

TI 82 Does it need the disk battery and 4 AAA batteries to work?


No. The calculator runs on the four AAA batteries. The lithium battery is solely to retain the contents of the memory while you change the AAA batteries. If you don't care about retaining the memory, you don't need the lithium battery. You do, however, need the AAA batteries to use the calculator.

Re : " Both units Garmin Rino 110, overheat and flatten the batteries within 2 hours"

That is a factory defect related to a bad contact inside the unit.

If you contact garmin and insist to talk to a supervisor (second line) you can have both Rinos replaced.

Ensure it is not a bad batteries problem first testing a replacement battery, both batteries may have deteriorated at same time.

Buy first a replacement battery at Garmin eTrek, Rino 110/120 NiMH Battery,

If that does not solve the problem call Garmin:

Batteries die quickly - unit gets hot


You may have a bad or shorted battery pack. You might try replacing it to see if the problem goes away. It would be normal, while charging for a battery to get warm. But not hot. Rechargeable batteries have a life expectancy of 18-24 months.

By reading a number of forums, I've found that there was a WAAS satelitte update (bug), that causes this foul up.
The only solution I've been able to arrive at is DISABLE the WAAS feature, as no Garmin Update/patch (for Rino120) has been made available.
To shutoff the WAAS feature press your [Page] button until you arrive at the "Main Menu"
go down until your on the "Setup"(hammer)
go in (by pressing in, on the directional button)
go down until your on the "System"(gears)
go in (by pressing in, on the directional button)
go down until your on WAAS, go in and select the Disabled
go up to the "X" (top right) press it, then you can [Page] button anywhere you want from there.

----------
Wonder what WAAS is?

Take care.

PS- Garmin if you read this....I would like to have my WAAS back, and since I registered for updates, back in 2005, why didn't I get an email from you telling me about this issue (when it happened and provide a solution - at the same time :: even a work around as I've posted here)

To make un full reset


Hello Rahooty,

There is no way to set the date and time becayse the system clock in your Garmin Rhino 120 should be updating based on the information it receives from the GPS satellites. The radio should auto locate itself within about five minutes of being turned on providing it has a clear view of the sky. Once it sucessfully auto locates the radio's clock and position should reset. There does not appear to be any other reset built into the device.

Try taking the batteries out for at least 5 minutes. Then, reinstall the batteries, turn the unit on, and give the unit 5-10 minutes to auto locate. If it doesn't, you may need to contact Garmin support for additional sevice.

Best Regards,
Ken
